Hello Martin,
I don't know if this would be of interest to you, there is an informal motorcycle meet at Jack's Fish and Chip shop on the main A30 in Bagshot at lunchtime on November 13th. It is listed in the LDMCC magazine as a run for Surrey/Hants members. There are usually a couple of Dragonflies there - a stone and green one and a black and silver. If you do attend, make yourself known to the owners, they will make your Dad and yourself most welcome, and will be happy to chat endlessly on matters 'Douglas'.
Regards,
Eddie.
P.S. The LDMCC secretary has been away on holiday recently, and may still be catching up on recent correspondence.
